Perrin 1 Piece Divorced Down pipe install progress

Well starting off to install my Perrin 1 Piece Divorced Down Pipe, I did all the required research. Checking install docs, heat shield removal, bolt locations, TMIC removal etc etc.

 

The part that scared me was removing the TMIC. Once I actually looked at what needed to be removed, and removed it, the TMIC was in fact the easiest part to remove. Once I got the heat shield off I started on the stock downpipe turbo flange bolts.

 

4 out of 5 came off without issue. Bolt 2 (center one of the top 3) was seized after about 4 turns. The car has 23,000 kms, and has only seen 1 winter. Without a spare (none were included in the kit) I was done for the night. Not worth risking shearing a bolt off with no spare. I bolted everything back up, and went inside to watch the Detroit/Pitsburg Hockey game.

 

Go Crosby !

 

 

Update when I have a spare bolt inhand.

 

Pics to follow.

Few pics of my downpipe, thanks FredBeansParts!

Spray some penetrating oil on all bolts before wrenching. I did the same on my 2006 LGT which has gone through several Quebec/Ontario winters and I had no resistance on any bolt or nut.

Completed today. Pics and video to follow..

 

 

ended up snapping the bolt i didn't want to, but also pulled out one of studs... stupid design..

Get a tune for the DP??

Install complete

 

Im super amazed at how quick the spool is now. Never would have thought, stage 2 is the best investment so far.

 

Mods are as follows;

The actual process of taking off the down pipe is simple

 

2 bolts at the mid pipe ( the ones with the springs) 2 down pipe mounts that are on the tranny (2 bolts) and 5 bolts on the turbo housing, as well as the o2 sensor

 

stock dp removed

Dumbest design ever, the waste gate hits a brick wall (on the stock DP)

Videos (right click save as) these were shot with a digi cam, real video coming soon.

 

 

First start up. My brother is talking to my dad about voiding warranty and stuff, dad asks if we are going to blow shit up, brother starts explaining that we didn't change anything pre-turbo, or internals. My dad is shooting the video, hence the coffee. I proceed to stand behind the car to check it out, asking my brother to step on it a few times. Hes amazed at how quick the boost gauge reads when you step on it now.

On the way home from a night of cruising, at 0:41 you can here a neat backfire.

A rear video of moderate acceleration... wind noise gets bad 1/2 way through to the end, but you get the idea.

Im so happy.

On a side note, the stock IC is the biggest piece of crap I have ever seen

You going to put the heat shield back on?

Suggestion: Put a shop rag into the turbo outlet when you remove the I/C to prevent stray parts from entering.

what did you use to mount the perrin dp to the stock catback? did you buy a 3" to 2.5" reducer?

Nice pics for the install. I only removed the stock dp to gut the first cat. I didn't need to remove the TMIC, but I ran into the same problem with the factory crossthreaded bolt. Ended up having to cut it off with a torch

hey jason, thanks for the comment, we share the same name

 

i guess I was lucky, I said to my bro "do you think we will need to use a new bolt" and with the next turn of the wrench we snapped the nut off after the threads came out of the turbo side..

 

i guess we were really lucky

I'd say you lucked out.. We tried a bigger wrench, breaker bar, penetrating oil, finally got the torch out figuring we could heat it and then use a wrench to get it off.. None of that worked and we ended up cutting it off with the torch, and using a new bolt.

wpg...

 

thats where im from :O

the perrin down pipe mates to the factory midpipe without a reducer.

Suggestion: Put a shop rag into the turbo outlet when you remove the I/C to prevent stray parts from entering.

 

thats weird. I did, in that picture its not there, very weird..

 

ohnoes!!!!!!!
