#1 V12 sereis 3 Exhaust ..straight or std?

Post by AdrianS » Mon Apr 08, 2019 2:19 pm

HI

I have a 1971 series 3 2+2 FHC e type and in the process of rebuilding the rear brakes and suspension, in removing the exhaust i discovered holes!!! so looking at a stainless steel replacement... i have choices! .. either a standard with standard silencers or one with straight through centre boxes with only minimal silencing... part of me want to keep original, but there's curiosity as to what effect the straight through system would have???

anyone done this or got any first hand experience?

Why not look at Roger Bywater's site for two types of performance stainless system?

Google AJ6 Engineering. Good kit from a no-BS guy.

Get your gentleman's gentleman to telegraph Bywater and his blacksmith will sort something out for you. I'm sure there will be some spare room on the Titanic, or that new-fangled Hindenburg Zeppelin thing.... :P

The best arrangement I have found, and the cheapest, is standard Jag mufflers, then straight pipes from there. Get rid of the resonator under the trunk....does nothing. Nice, but still subdued sound, performance the same, and your done with the rust prone resonator. Go on line and find a fashionable pair of exhaust tips. Any good muffler shop can make the pipes.

I have the Bell SS system but have replaced the rear resonator with straight through 2" pipes. SS off course :bigrin:
The sounds is so much better than the full Bell system and you can opt for straight ends or have them bend like the S1 and S2 tail pipes.
The guy that bend my pipes wasn't observant enough with the angles, but that will be rectified.

Hi thanks for the advice, im starting to think that way, but want to keep the 4 pipe fan tail so looks original so may get a 2 into 4 final piece made also to keep that original look....or just connect to 2 of the fantail pipes!!! might be cheaper!

Personally keep it original preferably stainless with rear box and 4 flute tail pipe. (the twins were naff)
A complete stainless system is quite noisy anyway as the original mild steel pipes were partly double skinned if I remember rightly.

thanks that was the conclusion i was coming too, looking at buying parts added up to more than a whole system (crazy)...so just took delivery of a complete Bell SS system ... just got to put rear cage etc. back in..after fitting new ebc brake discs etc and extending my brake pipes to make bleeding easier..... only transmission sump gasket to replace then exhaust can go on....keeps me out of trouble!! :lol:
